MDEV-5113 Wrong result (extra row) and valgrind warnings in Item_maxmin_subselect::any_value on 2nd execution of PS with SELECT subquery When setting Item_func_not_all::test_sum_item or Item_func_not_all::test_sub_item, reset the other one to NULL - they can never be set both. When a PS is reexecuted, different executions might be optimized differently and a wrong test_su*_item might stay set from the previous execution. 2013-11-12 15:02:25 +01:00			`CREATE TABLE t1 (b INT NOT NULL);`
